Birchwood & Trower (2006) called on researchers to try to identify the active agents in CBT for psychosis and to look at ways of increasing its effectiveness. They list a number of interesting and useful areas for further study. A key area which was not included in the list, is why so many potential therapy candidates do not participate in therapy at all. We believe that this, the engagement process, merits consideration.

Our own experience in conducting a RCT is that it is very difficult to recruit people with first episode psychosis to participate in psychological treatments. Yet, once people do engage they seem to embrace it whole-heartedly and others report similar findings as evidenced by the low drop out rates. Although disappointing, the level of refusal for psychological interventions should be seen in the light of other treatments for psychosis. For example, Lieberman et al’s (2005) RCT of atypical anti-psychotics had a 74% dropout rate over 18 months.

While the debate regarding the effect size of psychological treatments is undoubtedly important; given the low level of engagement, perhaps we need to evaluate the methods we use to engage patients with psychosis in psychological therapy. Other disciplines have investigated recruitment and engagement techniques. For example, in gynaecology, Wiemann et al, (2005) proposed 8 techniques for increasing recruitment among a high-drop out subgroup. Reviews such as Bryant and Powell (2005) that looks at recruitment incentives for staff or Edwards et al, (2002) that looks at response rates to postal questionnaires are early models of a potentially new area of research.

There is a need to engage, motivate and interest psychosis patients in their own care. Perhaps, we need studies of the reasons why people choose to participate or not in psychological therapies. The role of the public understanding of psychiatric illness in the engagement process might be a good place to start.
